Final article in Paul O'Connor's series on double weaves in the Minnesota Weaver. It explains eight-harness two-block double weaves ("double-double weaves"), covering threading in two colors per block, tieups, color-and-layer planning, and the number of color patterns a single warp can give. It then outlines Karon Rucker's "flying bridge" technique, in which weft floats between layers so the cloth can be folded off the loom into dimensional forms. Includes small drafts, diagrams, photographs of the author's work, and a bibliography.
